NRL developed the Cyclotron Particle Accelerator, which produced beams of neutrons, protons, deuterons, and helium and carbon nuclei with energies up to 80 million electron volts. These particles were used for the study of radiation damage to
reactor materials, for neutron radiation therapy for cancer, for the production of radioisotopes, and for general radiation
research. The NRL Cyclotron was decommissioned in 1985.
